Septic tank Eurobion - new generation cleaning system

The Eurobion septic tank is a domestically produced autonomous sewage system. Designed to serve private houses, dachas, cottages, hotels with a small number of guests. According to the manufacturer, the degree of wastewater treatment in the unit reaches 98%. The installation is compact, easy to operate, and does not require frequent special maintenance.

The developer and manufacturer of Eurobion septic tanks is NEP-Center LLC. The company has its own research base. Its employees develop and implement various wastewater treatment systems. The company's products have all the necessary certificates of conformity.

Eurobion septic tank body design

The body of the Eurobion Art septic tank is made in the shape of a cylinder. It was the first cylindrical polypropylene station on the market. The pressure is distributed evenly throughout the cylindrical body, so it better withstands loads. Integral foamed polypropylene, three-layer. Between the sheets of homogeneous polypropylene there is a porous layer. The advantages of this material are good thermal insulation and low weight.

The body has one weld across the entire thickness, and the strength of the seam reaches 80-90% of the strength of the material. The case is equipped with stiffening ribs along the entire length, this is additional protection against deformation. The bottom has protruding edges with lugs, so the septic tank is stable in high groundwater.

Design and principle of operation

The manufacturer claims that Eurobion septic tanks are advanced local treatment systems of a new generation, the development of which takes into account and corrects the shortcomings characteristic of sewerage installations. Regardless of the drainage speed and the volume of salvo discharge in the units, liquid flows smoothly from compartment to compartment and at the exit from the system.

Eurobion septic tanks are a vertically located container equipped with stiffening ribs and supporting elements (lugs) to impart stability to the structure. The internal space is divided into two compartments in which special equipment is mounted. In the upper part of the container there is a neck for technological maintenance of the installation.

The manufacturer does not inform consumers in detail about the operating principle of the installation. But, based on the design of the device, it can be assumed that the process of wastewater treatment in the Eurobion biological treatment plant consists of the following stages:

1. The liquid flows by gravity through the inlet pipe into the first chamber. This compartment is both a receiver and a primary aeration tank. Large waste particles and debris settle in the chamber (an intermediate bottom facilitates a more efficient settling process). At the same time, air is pumped into the compartment using the aerator. It is necessary to maintain the vital activity of aerobic bacteria, with the help of which biological waste is broken down.
2. Partially purified water enters the second chamber. It continues the processes of settling and decomposition of biological components with the help of bacteria. The remaining solid fractions settled at the bottom from this compartment are pumped into the first chamber using an airlift. This allows you to remove residual sediment from the container and replenish the bacterial colonies in the primary aeration tank. The biofilm formed during wastewater treatment is also removed from this compartment.
3. In the next stage, the liquid enters the tertiary settling tank. Its role is played by a pipe with an aero-drain built into it.

Note! If wastewater stops flowing into the unit, then purified water is not discharged. The liquid continues to circulate inside the device. A new portion of purified water leaves the installation only after resuming use of the sewerage system.

Model range of septic tanks Eurobion

Initially, the model range began with the Eurobion 2 and Eurobion 3 rectangular models (dimensions, respectively, 1x0.7 m, 0.7x0.5 m). These were gravity stations. These models were then discontinued. Their release was economically unprofitable. Mostly forced cylindrical modifications were sold. More material was spent on a rectangular body and such a septic tank was more expensive.

Today, Eurobion 5, 8, 10, 15, 20 models are produced according to the number of conditional users. The index R (radius) in the name means that the station is cylindrical. Eurobion 5 has one caveat: based on the norm of 200 liters per person per day, it must process 1 cubic meter. meter of drainage, but in practice its productivity is 900 liters. This is not critical, since the real average water consumption is slightly less - within 150-175 l/day.

Typically, in suburban areas, models from Eurobion 5 to Eurobion 20 are installed. There are models with higher productivity - for 30, 40, 50 conditional users, but they are used much less frequently. Models over 20 have a rectangular body and are simply called Eurobion, without the addition Art.

Characteristics of Eurobion 5R Art - the most popular model.

Lengthening the septic tank body does not affect the working volume in any way. Increasing the depth of insertion of the supply pipe is limited by the fact that the longer the body, the stronger the soil will press on it. In addition, the larger the diameter of the septic tank, the less rigidity of the body becomes, and, accordingly, the less elongation of the body without loss of strength.

Products from the market leader

Eurobion septic tanks are produced by the domestic company Yubas. Back in 2001, specialists from this company invented and patented a wastewater treatment system based on aeration tanks. At the same time, the manufacturer begins production of autonomous treatment plants under the Eurobion brand.

Currently, the Yubas company is considered one of the leading equipment for local sewage systems on the market. It annually releases new models of stations that are distinguished by their reliability and high level of wastewater treatment.

Comparison of septic tanks Round and Eurobion

In 2021, the Rusin station appeared. More recently, it was renamed Round. Today, 2 modifications are available, designed for 4 and 5 people, with gravity or forced drainage. The depth of insertion of the supply pipe from the zero ground level is up to 60 cm.

Round is an economical modification of Eurobion 5. The cost reduction is achieved by simplifying the design:

• There are no external stiffeners.
• The lid has no hinges (simply fits onto the body).
• There is no top edging (the lid protrudes 20 cm).
• Economical compressor.

At the Zagorod company you can buy a Eurobion Round septic tank from the official manufacturer.

The South Korean DongYang compressor is installed in Round. Eurobion Art used to be equipped only with Japanese Hiblow compressors, but today German Thomas compressors are also used. It is believed that Thomas is more reliable than Dong Yang, although the difference is not critical. Both compressors are efficient and durable. They serve, on average, 5-7 years.

The Round septic tank uses a Chinese UniPump Sub 2009 pump. The Eurobion uses a Dab Nova 180 MA pump (Italy, Hungary). In the Dub Nova pump, the float is mounted on a rigid rod (stage) and moves only in one plane. When turning the pump (when the station is turned on), the float may rest against the chamber wall and get stuck in this position. UniPump Sub 2009 is a standard design pump with a float attached to the end of the cable and moves freely.

Customer Reviews

Valentin:

Maybe we were so unlucky, but the joints of Eurobion are simply disgusting. Already at the time of installation, the seams began to fall apart, the workers had to solder again.

Sergey:

We installed VOC Eurobion six months ago. At first the smell bothered me, but within 3 weeks the station was up and running, no complaints, we were happy.

Michael:

We have been using the Eurobion septic tank in our country house for several years now. I like that you can take breaks from using it. No complaints.

Changes that have been made to the Eurobion ART station (since 2016)

A removable hair catcher has been added. This is important because hair clogs the station a lot. It is a tube with a soldered polypropylene rod. Installed in the receiving chamber. During service, the hair trap is removed and washed.

A special brush has appeared that is inserted into the channel sump. It also collects hair and other dirt. In addition, activated sludge settles on the channel settling tank. The removal of silt during volley discharges is less.

An inclined partition appeared under the false bottom between the aeration tank and the secondary settling tank. Before this, there was a partition between them to the bottom with a 50 mm hole. If there was no service for a long time, this hole became clogged. Now the cameras communicate through a wide gap and blockages are impossible.

A service airlift has been added for pumping out the septic tank with your own hands. This airlift is equipped with a special plug. To start pumping out the sludge, you need to remove the plug. There is a trick: you need to unscrew the tube from the compressor distributor that goes to the aerator, and put a plug from the airlift in its place. This will shut off the air supply, and pumping sludge through the airlift will go faster.

Scheme of operation of the Eurobion ART septic tank with improvements after 2021. An inclined partition appeared, the airlift between the secondary settling tank and the aeration tank disappeared, and a service airlift appeared.

Main advantages of the installation

Advantages of using Eurobion units:

• environmental safety due to high quality cleaning;
• long service life ensured by the strength and corrosion resistance of the plastic case;
• possibility of use both constantly and periodically, which is very convenient for summer residences and summer cottages;
• increased volume of salvo discharge, allowing the installation of any plumbing fixtures in the house;
• ease of use: no odors or noise.

Eurobion septic tanks are an innovative solution to the problem of safe disposal of sewage. The use of modern polymer materials for the manufacture of parts has significantly increased the reliability of the installation and its service life. The stations are compact; you don’t have to allocate a large area to install them on your site.

Complete set and additional equipment of Eurobion stations

The standard septic tank package includes:

• Frame
• Technological equipment: aerator, recirculation airlift, etc.
• Compressor.
• Polypropylene elbow 110x15°.

I must say that the equipment is one of the weakest among other stations. There is no pipe for inserting the supply pipeline and there is no polypropylene rod for welding the pipe. Also, the Eurobion does not come with a hazard warning lamp.

Optional equipment. Not included in the standard package and must be purchased separately:

• Ultraviolet lamps (UV) for waste disinfection. They are installed only in elongated models with forced drainage (the drain is pumped through the lamp).
• You can also install the Bioguard system in Eurobion. This is an alarm that is triggered when there is a break in the electrical circuit and signals that the compressor has stopped working, including if it is stolen.

Installation

Since the Eurobion biological treatment station is a rather complex technical device, during its installation it is necessary to take into account and comply with many special conditions and regulatory requirements. In addition, certain skills will be required when installing and connecting pipelines, electrical equipment, etc.

Attention! In order to avoid mistakes and miscalculations that could lead to improper operation of the septic tank, the manufacturer recommends that the installation be installed by a specialized organization.

If the user, having the required amount of knowledge and skills, decides to carry out the installation himself, then when carrying out the installation it is recommended to use the diagram from the manufacturer.

Turnkey installation of autonomous sewage system Eurobion

Pre-installation measurements and cost estimates

Before installation, a survey engineer is scheduled to visit the site. He arrives on the agreed day and determines:

1. A place for a septic tank, taking into account the permissible distances to the road, house, trees (up to 3-5 meters) and sources of drinking water (up to 50 m).
2. Soil type and groundwater level. Taking this into account, the specialist chooses a method of drainage. In sandy or sandy loam soil with low groundwater, Eurobion is installed with gravity drainage into a filter well. For clay and/or high ground, a forced modification with a drainage pump is chosen, with pumping into a ditch.
3. The depth of the drain pipe from the house. This affects the selection of modifications according to the insertion depth. The pipe must be led to the septic tank with a slope of 2 cm per meter of route. The distance to home is taken into account. If the drain pipe is located deep, then choose Eurobion Midi, Long or Superlong septic tanks with an elongated body. With such models you can cut the pipe deeper.

The measurer also discusses additional work with the customer. It happens that you need to cut down bushes for a septic tank. Sometimes you can raise the outlet of the fan pipe so as not to install a more expensive extended station. This work is also performed during installation.

After measurements and discussion with the customer of all the nuances, an installation diagram is drawn and an estimate is drawn up. The Zagorod company calculates estimates directly on site, within 45 minutes after measurements. Our company includes every last detail in the estimate. The total cost of installation is immediately clear. We carry out delivery strictly according to the estimate, that is, we bring everything that is needed for installation.

Installation of housing and pipelines

The pit is dug 50-60 cm longer than the length and width of the septic tank, so that there is 25-30 cm left on each side for sprinkling with sand. A sand cushion 10 cm thick is poured at the bottom of the pit.

During installation, the septic tank is leveled. The permissible slope is up to 5 mm per 1 m. The supply pipeline is cut into the receiving chamber, in which a movable false bottom is located.

Then I sprinkle the septic tank with sand and spill it with water. All chambers communicate with each other, so water can be poured into any compartment without the risk of damaging the structure. Backfilling and filling are carried out in stages. First, pour water to a depth of 30 cm, then sprinkle the septic tank with sand and compact it, then fill it again, sprinkle it, and so on until the outlet of the aerodrain system. This water level is called working.

Sanding and watering

The height of the insert from the bottom is 1.6 m from the bottom for any model. The recommended insertion depth for a standard station is 30 cm. In this case, during volley discharges, the supply pipe will not be flooded. The insertion is made using a crown and a hot air gun. A hole is cut out using a crown, and the pipe is sealed with a polypropylene rod using a hairdryer. The input is sealed.

Correct insertion of the pipe

Installation of a compressor and pump in Eurobion forced septic tanks

The compressor is installed in the electrical compartment and plugged into a power outlet. The pump in forced modifications is installed in a chamber for purified water. The pump cable is inserted into the compressor compartment and the plug is plugged into the second socket.

Connecting the compressor and pump

If desired, the compressor can be installed outside the septic tank. This is not difficult to do, but there is no point in such a setup. It is generally not recommended to install a compressor in a living room - there is not enough oxygen in it, in winter warm air enters the pipe and condensation forms on it. Installing a compressor in a heated room is only possible with constantly running supply ventilation.

The compressor is connected through a HDPE pipe 25. Plastic cone nozzles are provided for this purpose. The remote compressor is plugged into an outlet in the room where it is installed. When placing the compressor inside the septic tank, the cable is laid in a corrugation, inserted into the compressor compartment and connected to the receiving block. Together with the compressor, an alarm is installed, a lamp and a float are hung in the receiving chamber.

In the technical data sheet, the manufacturer strongly recommends venting exhaust air through the supply pipeline. It is best if the air is removed through a vent pipe leading to the roof of the house. This will avoid the breakdown of water seals, although a septic tank can operate effectively without such ventilation. The exhaust air exits normally through the holes in the cover.

Installation of structures: work procedure ↑

Installation of treatment plants must be carried out by specialists. The structures are installed strictly according to the technology developed by the manufacturer. Companies that officially sell Eurobion autonomous sewage systems have permission to carry out installation and commissioning work.

Preparing the pit ↑

Station installation diagram

The system is installed in a prepared pit:

• If the soil is dense, with a low level of moisture, then it is allowed to install the housing without constructing a protective structure.

• In clayey rocks saturated with water, preparation is required: formwork is built from rough boards around the perimeter of the pit.

Installation in a pit with reinforced walls

The bottom of the pit must be filled with concrete with reinforcing mesh, or a floor slab must be installed. The thickness of the base is from 10 cm. Along the edges of the area where the housing is planned to be fastened, metal hooks are fixed into the solution.

Installation of tanks and launch of systems ↑

The structure is attached to the base with metal wire or fittings, threading it through the hooks and connecting the wire to the factory fasteners at the bottom of the case.

Insulated housing in the process of backfilling

The walls are insulated with sheets of foam plastic or roll thermal insulation for external use. The housing must be installed strictly vertically. Using a level, check for deviations from the horizontal line and adjust the position if necessary.

Station on the site

Backfilling is performed exclusively with sand. The layers are compacted. After installation is completed, the upper part of the housing with an inspection cover remains above the surface. Specialists fine-tune the operating parameters and launch the system. Adjustments may be required within a few weeks after the first launch.

Video: how Eurobion stations are assembled ↑

An interesting video about the full assembly and startup cycle: from welding the body to the first start-up of the installed station.

Autonomous sewage system Eurobion, according to reviews from owners, causes virtually no trouble in maintenance. The simplest possible design and advanced treatment technology make it possible to safely discharge treated wastewater into water bodies or onto the terrain without the risk of groundwater contamination. All parts and consumables are produced by the manufacturer - finding a replacement part is not difficult. To obtain a guarantee for the operation of the system, the following condition must be met: installation and connection must be carried out by representatives of the manufacturer.

Eurobion septic tank service

Maintenance is not just pumping out sludge every 6 months, but also regularly monitoring the operation of the station. Many users do not call a service engineer until they have problems cleaning their drains and there is an odor. This attitude leads to high costs for station repairs. But even after several years without maintenance, both a service specialist and a vacuum cleaner are often needed. The channel settling tank, airlifts, film degasser, and air drain tube become heavily clogged.

The septic tank is pumped out in several stages so that it is not pushed out by groundwater. All working elements are sorted and washed. In the old version, it can be difficult to clean the overflow between the settling chamber and the secondary settling tank. In this case, intense movements of the false bottom up and down help. But it helps with minor blockages. If it is strong, then you can break the hinges for attaching the false bottom.

You can service the Eurobion septic tank yourself:

Once a day, check that the hazard warning light is not on. This means that everything is in order with the sewer.

Once a month you need to open the lid of the septic tank and carry out a visual inspection, catch floating debris from the aeration tank and also check whether the alarm system is working (to do this, simply lift the float). When inspecting, you need to pay attention to the condition of the water at the outlet. It should be light and odorless.

Signs of normal septic tank operation:

• The main airlift drains water into the receiving chamber (this can be seen when the water level in the receiver is normal).
• Aeration elements saturate the water with oxygen (rising air bubbles are visible).
• There are no whistling sounds (if there is, then this is a sign of poor fixation of the injectors; they need to be tightened).
• There is a flow of water towards the film degasser.
• The aero drain works normally (if not, then you need to clean it).

Once every 6 months, maintenance is carried out with sludge pumping out. It is necessary to remove and wash the brush and hair catcher, blow out the main airlift, clean and rinse the filters on the compressor.

It is recommended to replace worn compressor membranes once every 3 years. The aeration element is replaced once every 10 years. A full service with pumping out sludge and garbage is performed once every 5 years.

Station cost

The price for a Eurobion septic tank depends on the model and modification.
The most popular among owners of private houses are models 5, 6 and 8, which are capable of processing 0.9, 1.2 and 1.6 m3 of wastewater per day, respectively. In the simplest modifications they cost approximately 72,000, 95,000 and 130,000 rubles. Forced removal of wastewater and the need to deepen the inlet and outlet pipelines increase the cost of the product.

If you order a turnkey septic tank, its price will increase by about 25-30 thousand rubles.

Price ↑

Today, the cost of these septic tanks remains one of the most affordable on the market. This is due to the simplicity of the design and the use of domestically produced components.

However, this fact does not affect the quality guaranteed by the manufacturer.

Advantages and disadvantages

According to owner reviews, Eurobion autonomous cleaning systems have the following advantages:

1. A high degree of purification allows you to use recycled water for technical needs, for example, watering a site.
2. A good indicator of the volume of salvo discharge, compared with other domestic manufacturers. Thanks to the three-stage Aerodrain system, even compact models in emergency situations can take up to 600 liters at a time, despite the fact that their nominal salvo discharge is 200 liters.
3. The case material is resistant to sudden temperature changes and mechanical stress.
4. Easy to operate and maintain. All work can be done independently.
5. Thanks to the use of the aeration cleaning method, there are no unpleasant odors.
6. Compact sizes. The cylindrical body without dead spots allows you to make the most of your workspace.
7. There is a possibility of downtime after 8 months of continuous operation. If the duration of the interruption in operation does not exceed 90 days, mothballing of the station is not required;
8. Possibility of remote control.

The main disadvantage of stations, inherent in all aeration installations, is the dependence on electricity, which is necessary for the operation of the compressor and pump.

Some negative reviews about Eurobion septic tanks are related to the difficulty of removing solid sediment.

The disadvantages of the designs also include the poor location of the ventilation hole in some models. It is located on the cover above the compressor, which can lead to moisture penetration with subsequent failure of the electronic components of the station.

Users note the station's sensitivity to the type of waste. The manufacturer recommends using neutral or biodegradable detergents so as not to destroy bacteria in the septic tank.

Operating principle of a biological treatment plant

Cleaning of household waste in Eurobion aeration units is divided into stages:

1. The wastewater enters the receiving department, equipped with an aeration tank. Injected air bubbles mix the liquid, crush solid impurities in it, and also serve to maintain the vital activity of microflora. Here, the heavy fractions are separated from the light fractions and settle in a settling tank, and the liquid part of the wastewater is subjected to primary purification by bacteria.
2. The clarified wastewater is fed into the second chamber, where aerobic treatment continues. An airlift is installed in this chamber, directing excess liquid along with activated sludge back to the receiver.
3. In the third chamber, final cleaning occurs with the separation of undissolved waste and the removal of purified water to the outside.

A constant liquid level is maintained in the Eurobion septic tank. In the absence of new waste flows, the liquid circulates between the chambers. Only the excess is discarded.

Which septic tank to choose

When choosing a suitable model, it is necessary to take into account the number of permanent residents and the average water consumption per day. Also, you should pay attention to the permissible salvo discharge. Although the manufacturer states that it is permissible to exceed it in emergency cases, you should not abuse this opportunity so as not to wash out the microflora.
